I experienced exactly the same troubles. => Pre-setting a correct aspect ratio in the drop down list speeds up the process somehow (you just have to set one dimension, the other often gets right). > What would be very convenient for my use case: Using the keyboard to > give a size (e.g. 1600x900), and then use the mouse to drag the crop > rectangle to the appropriate position. So far, what I do is set the size via mouse manually once then create a style with the correct size for other pictures. But that's a fragile hack because the style (probably rightfully) stores the crop area as a fraction of picture dimensions or similar, not as pixels. So, a preset for this purpose only works well on other pictures of exact same dimension. Alas, picture dimensions vary a lot per camera, orientation, shoot-time settings. For example, a JPEG from a Nikon camera, even at full resolution, does not have exactly the same dimensions as the RAW file (Nikon D60 RAW 3899x2625 JPEG 3872x2592, Nikon D5200 RAW 6034x4036 JPEG 6000x4000). So in practice one has to create one style per situation (I currently have 16...), or AFAIK just do it manually all the time. > Is there some way within the crop and rotate module to define exact crop > size by means of numerical keyboard input? I would appreciate such a feature! Given that typing works in all sliders and more (even in the aspect ratio drop down list, type 22:7 for example), one idea would be to type e.g. 1600x900 at rectangle corner drag time. Other software (like Google Sketchup) has similar features. Alternatively, including in the iop module a box showing the position and another showing the size ? People who never care might fear UI clutter.
